ONYX C20 Commercial Treadmill

The ONYX C20 is a full commercial-grade treadmill engineered for facilities that demand performance, durability, and daily reliability. Whether you're outfitting a gym, hotel fitness centre, corporate wellness space, or school athletic facility, the C20 delivers the power and build quality your users expect — and your facility requires. Rated for continuous commercial use, built with welded heavy-gauge steel, and powered by a 5.3HP AC motor, this is the treadmill that works as hard as your members do.

PRODUCT FEATURES

• 160cm x 58cm Oversized Running Belt — A wide, full-length running surface that comfortably accommodates users of all heights and running styles, making it ideal for high-traffic commercial environments.
• 5.3HP AC Peak Commercial Motor — Unlike DC motors found in home treadmills, the AC motor in the C20 is engineered for hours of continuous daily use without overheating — perfect for busy gyms and hotel fitness rooms.
• 0–16% Motorised Incline — Surpasses the standard 10% incline found on most treadmills, giving users the ability to simulate steep hill training and maximise workout intensity.
• 180kg Maximum User Weight Capacity — Confidently supports users of all sizes, a must-have for any commercial facility serving a diverse membership base.
• Non-Folding Commercial-Grade Deck — Fixed welded deck construction is the industry standard for commercial use. Unlike folding home treadmills, the C20's rigid frame provides superior stability and withstands the repetitive demands of commercial operation.
• Self-Lubricating Running Deck — Reduces maintenance time and cost. No manual lubrication required — ideal for facilities where equipment upkeep needs to be simple and efficient.
• Heavy-Gauge Welded Steel Frame — Constructed to commercial specification, this frame is built to last in high-traffic facilities for years of daily use.
• 1–20km/h Speed Range — Covers the full spectrum from walking rehabilitation to high-intensity sprint training, catering to every fitness level in your facility.
• Contact Grip Heart Rate Sensors — Handlebar-integrated pulse sensors allow users to monitor heart rate without wearables, supporting safer, more effective workouts.
• Computerised LED Console — Displays time, speed, distance, calories, heart rate, and incline. Includes multiple pre-set programs, quick-adjust speed and incline buttons, and a storage tray for tablets, phones, keys, and water bottles.
